Interesting topic.
Inspiration comes in many forms and there's a ton to be said for all of the previous posts, but I'll throw something a bit different out.
Do consider the beautifully done "coffee table" book (with companion CD) documenting the build philosophy and thought processes of Danny Ferrington. Some may dismiss him as a top-tier builder, but more than anything else, it challenges those who feel like they've reached an understanding or the art of luthiery to examine the entire methodology of instrument construction.
Worth tracking down, I consider this truly as a "Hove you ever been experianced?" read. It might stay on your table a long time, but it will stay in your mind much, much longer.
